“The Doctor: This is bad, I don’t like this. [kicks console and yells in pain] Never use force, you just embarrass yourself. Unless you’re cross, in which case… always use force!
Amy: Shall I run and get the manual?
The Doctor: I threw it in a supernova.
Amy: You threw the manual in a supernova? Why?
The Doctor: Because I disagreed with it! Now stop talking to me when I’m cross!”
